With profits near record levels, Delta Air Lines is sharing some of the wealth with its employees through 6 percent raises that will take effect next year, the company announced Tuesday.

Starting April 1, Delta’s flight attendants and other ground workers, about 65,000 employees total, will receive a 6 percent raise. About 1,000 of those workers are based in Dallas, the company said.

When coupled with the 18.5 percent raises the company handed out in 2015, Delta’s front-line employees have seen their base pay increase 25 percent over the last two years.

The company also announced Tuesday that it’s increasing its contribution to employee retirement accounts to 3 percent.

“I’m proud to say that Delta has led the industry in compensation increases for our employees the last several years and has set the standard for other airlines to follow,” CEO Ed Bastian said in a message to employees. “This increase, coupled with our profit sharing program that also leads the industry by workgroup, enables us to maintain industry-leading total compensation among our global competitors.”

Delta’s pilots are not eligible for the increase, although the group is voting on a new contract that would raise pilots' pay 30 percent over four years. The company's flight dispatchers, who are unionized, and its management executives also are not eligible for the raise.

After a decade of financial struggle, airlines have been on the rise in recent years thanks to consolidation and low fuel costs, with the industry posting a combined profit of $26 billion in 2015.

While much of those profits have been returned to shareholders or invested in new planes and amenities, employees have seen their wages rise with new contracts and in some cases, blanket raises handed out by the carriers.

In March, American Airlines reinstated profit-sharing for its employees and a 6 percent pay increase for flight attendants. In August, the Fort Worth-based carrier announced pay raises for 30,000 mechanics and ground workers ranging from 15 percent to 55 percent.

At Southwest, the pilots union and flight attendants union recently agreed to new contracts that will raise their pay 3 percent to 6 percent over each of the next several years.
